摘要

在酒石酸体系下,采用原位聚合法合成还原氧化石墨烯(RGO)/一次掺杂态聚苯胺(PANI)纳米复合材料,经氨水解掺杂后,再对其进行二次掺杂得到RGO/二次掺杂态PANI纳米复合材料。利用傅里叶变换红外光谱、紫外光谱和扫描电子显微镜测试技术,分析了不同配比RGO/PANI纳米复合材料的官能团及表面形态特征。并通过电化学测试技术研究了RGO/PANI薄膜在模拟海水体系中的防腐性能。结果表明,还原氧化石墨烯与苯胺质量比为1∶15时产物形貌及防腐效果最佳,其中,RGO/一次掺杂态PANI的缓蚀效率可达70.2%;RGO/二次掺杂态PANI防腐性能更优,缓蚀率高达75.6%。
        Under the tartaric acid system, reduced graphene oxide(RGO)/primary doped polyaniline(PANI) nanomaterials were synthesized by in-situ polymerization method. After dedoping with ammonia, RGO/redoped PANI nanocomposites were obtained by redoping. The functional groups and morphology of different RGO/PANI nanocomposites were analyzed by Fourier transform infrared spectroscopy(FT-IR), ultraviolet-visible spectroscopy(UV-Vis) and scanning electron microscopy(SEM). The anticorrosion performance of the RGO/PANI films on the low-carbon steel was tested by electrochemical measurement technology in the simulated seawater system. The results show that the RGO/PANI nanocomposites have the best morphology and the anticorrosion performance when the mass ratio of reduced graphene oxide and aniline is 1∶15, the anticorrosion efficiency of RGO/primarily doped PANI can reach 70.2%, the RGO/redoped PANI has better anticorrosion performance than the RGO/primary doped PANI nanocomposites, its anticorrosion efficiency is up to 75.6%.
